Mac OS 10.8.2 update, corrupts FileMaker 11.0v4 files.
Operating system version
Mac OS 10.8.2
Description of the issue
Today I have upgraded to Mac OS 10.8.2, and when I tried to open two large FileMaker 11.0v4 files the message "files have been damaged or tampered with." How could this happen with updating the system and not moving the FileMaker files from the desktop. What can I do now?
Steps to reproduce the problem
I went to "Get Info" under Finder-File, and found the FileMaker files were already open to both Read/Write. I also looked up known solutions, and found nothing for FM11.0v4.
To find a solution to the problem.
Thanks, Jim Vine
